Chapter 274 If you don’t understand, I can teach you.
Qin Baoshan is also a person who keeps pace with the times. He can still understand and digest the knowledge Qin Tao instilled in him.
The issue of patents is very serious. If it is only used domestically, foreigners will not be able to win if they come to China to file a lawsuit. However, if they want to mix in the international market, they may be confused by others. Bankrupt.
At one time, those MOSS cans they had were copied from surveying and mapping!
Qin Tao smiled: "Old man, you are finally smart."
“I have always been very smart!” Qin Baoshan said to Qin Tao: “How do you plan to solve this problem?”
“Aren’t we solving it?” Qin Tao said.
The issue of patents had already been taken into consideration by Qin Tao when they mapped the MOSS cans.
In the world, only the Norwegians have the patent for the MOSS tank natural gas ship. The little-known Mingzhou Shipyard has also built this kind of natural gas ship. So, is it an infringement?
Norwegians definitely need to pay attention and investigate, but this will take time!
At present, we have only delivered the first natural gas ship, and there are still orders for three or four ships on hand, which are under production. The Norwegians want conclusive evidence, which will take time.
By the time the Norwegians were sure and went to the nationality court to file a lawsuit, they had already fully switched to the production of membrane natural gas ships!
Qin Tao spent huge sums of money to transform, on the one hand because of the advantages of membrane-type natural gas ships, and on the other hand, to avoid patent issues. If the Norwegians want to cause trouble, they should go to Dazhou Company. By then, Dazhou Company will just start building natural gas ships with MOSS tanks.
Qin Tao has dug countless holes, but he doesn’t believe that Dazhou Company will not go bankrupt!
Our counterparts in other countries will be treated as if they are brought down.
Qin Baoshan also quickly understood that Qin Tao’s intention was to fully switch to the production of such membrane natural gas ships in the future. This was an idea.
“But what if people hold on to our old boat and won’t let it go?”
“If we hold on to it hard, our group will probably change its name and let the previous group go bankrupt.” Qin Tao said irresponsibly.
If you want to litigate, you must have a partner, right? Just changing the name will perfectly solve the problem, claim? Infringement? The previous company is gone!
This trick has long been played out by some companies in later generations. After taking on a project and finishing it, as long as the money needs to be paid, the company will immediately change its name and location. After-sales and other things can be dispensed with. Find a corporate legal person? She was an old man and an old lady who had nothing but borrowed her ID card for a few dozen dollars.
Now, if the Norwegians go too far, Qin Tao can certainly escape.
Qin Baoshan was there, feeling a little emotional. He was an honest and responsible person, how could his son become like this? However, what his son did was for the development of the entire group, so he did not continue to express his opinions.
After arranging matters at the shipyard, Qin Tao embarked on the road to go abroad again. This year, he spent more than half of his time abroad and was extremely busy.
This time, they were going to France. Going out with Qin Tao were Zheng Ming, who was in charge of naval equipment, and Ma Ming, plus a translator, making the group of four people.
Ma Ming was very excited. He remembered clearly that when Qin Tao came to see him, they had a very lively conversation, and the next scientific research also had a direction. At this time, even on the plane, Ma Ming could not talk too much, but Ma Ming was still talking. Continuously.
"Mr. Qin, we started research after we talked to you last time. Currently, we have built a prototype of a twelve-phase generator in the laboratory and conducted various tests. We also discovered Defects of this generator.”
Ma Ming has always been a man of his word. Although Qin Tao only returned to Mingzhou to plan the launch of the Siamese aircraft carrier, it took less than half a month for Ma Ming to start researching the twelve phases. Although the generator cannot be used as an engineering prototype, it can be used for many theoretical studies.
"If the Navy is not in a hurry, we can develop a twelve-phase generator for ships within two years." Ma Ming continued: "This time we go to negotiate with the Germans, and we can ask some technical questions. .”
“Yes, this thing was invented by the Germans after all. They have a lot of experience, but we can’t be superstitious about them. There are priorities in learning and expertise, and maybe we can be better than them.”
Ma Ming smiled shyly.
“Yes, this thing was invented by the Germans. In those years, we fell behind!”
Speaking of this, Zheng Ming was very emotional.
When the alternator was first invented, it was three-phase electricity. Three fires and one zero have been used until modern times. However, in the use of ships, three-phase alternating current has always been insufficient. The rectified direct current has great pulsation and cannot be used. Compared with the stable DC power provided by the battery.
(On this point, you can take a look at the cassette recorders of the 1980s and 1990s. They were very quiet when using batteries, but there would be noise when using AC power. It was not until switching power supplies appeared later that the rectified DC power was of high enough quality. )
The generator on the warship is AC, and many of the electrical appliances on it require DC power, so this contradiction has always existed.
Then, a technician named Harrington suddenly had a whim: Since three-phase electricity is not easy to use, then simply put twice as many coils in the generator to make six-phase electricity, and the rectified DC electricity will be The pulsation will be greatly reduced!
(This explanation is too technical and requires drawing repeated sinusoidal curves. Compared with three sinusoidal curves and six sinusoidal curves, six sinusoidal curves are definitely more stable.)
In 1970, the Germans made this kind of industrial six-phase generator, and then it got out of control. Ten years later, they turned the six-phase generator into a twelve-phase generator. It was extremely perfect, and at the same time, it became a The leader in the field of multi-phase generators, it was not until the 21st century that fifteen-phase generators appeared, reaching the highest peak in this field.
So, if you want to import this kind of generator, you have to find the Germans. After all, even the United Kingdom and the United States do not have the relevant technology.
The long voyage passed quickly while chatting. Although Qin Tao was not a professional in ship power systems, he was the chief engineer of an aircraft carrier in his previous life and had a high position. Many of the things he said gave Ma Ming a feeling of enlightenment. .
Deco Electric Company, conference room.
"Guests from the East are very welcome. Your choice is the wisest." A smile appeared on Lambert's face: "Our twelve-phase generator is the most advanced product of this era, and it will definitely satisfy your needs. .”
“Mr. Lambert, before we purchase, I hope to know more about your twelve-phase generator technology, rather than just a few parameters.” Zheng Ming said.
After hearing this, Lambert's smile disappeared, and a serious look appeared on his face again: "I'm sorry, it's not that we don't want to talk about it, but because this technology is too advanced, even if we talk about it, you guys I don’t understand either.”
There is a hidden saying that he did not say. Of course we cannot say it because we are afraid that you will copy it!
This kind of exported generators all have seals. If they are damaged, it will affect the warranty. Moreover, the Germans are very confident that when Asians buy them back, if they are disassembled, they cannot be put back together!
Just like Asan, he bought their tank engine parts and went back to assemble them himself. As a result, the diesel engine that was originally capable of outputting 1,500 horsepower could not output even 1,000 horsepower in Asan's hands!
Assembly is also technical.
So, they are not afraid of these. Now, of course, it will not work if we ask them to explain the technology.
After Lambert finished speaking, he saw that all the Easterners present looked unhappy, so he continued to comfort him: "Actually, you don't need to understand these technologies in depth. You just need to buy our products. You can't go wrong!"
This guy sometimes plays bad guy and sometimes plays bad guy, showing the ugly face of the sales staff so vividly that Qin Tao couldn't help but sigh in his heart, hum, this company with great technology has such great sales.
However, since you don’t say it, don’t blame us for kicking the gym.
“You are pushing three blocks and four blocks like this, could it be because your generator has technical flaws and you are afraid that we will find out?”
There was some hesitation in the translation. Qin Tao waved his hand: "Just translate the next words according to the original words!"
"How is it possible?" Lambert said: "Our technology is very perfect, there cannot be any problems, what do you know!"
“Of course we understand that the biggest problem in the twelve-phase rectifier generator system is natural oscillation.” Ma Ming said.
"Natural oscillation? How is it possible?" Lambert's face also turned ugly. Are you here to buy a generator, or are you here to quarrel?
"Mr. Lambert, you can't. You don't understand things in this professional field. It's better to invite an expert." Qin Tao said: "Tell the experts the word "natural oscillation" and they should come."
Lambert walked out angrily, and soon, a middle-aged man with a mustache walked in: "Everyone, I am the engineer of the twelve-phase alternator, Erich. I am responsible for technical issues. We can guarantee that the inherent oscillation you are talking about does not exist at all in our generator."
“Really?” Qin Tao glanced at Erich and said, “Mr. Ma, we don’t know whether the Germans really don’t know, or they just pretend to understand. Tell them!”
"Hmm." Ma Ming said, took out a large-scale drawing from his briefcase, and spread it out.
Erich's arrogant look just now disappeared immediately. He looked at the design drawing in surprise: "This is impossible. How come this design drawing is the same as the design drawing of our generator system? Are you guys?"
Subconsciously, Erich meant that his top-secret technology had been leaked, but he did not say the words.
Leaking secrets, how is it possible? The twelve-phase alternator is the top secret of their company. Neither the United Kingdom nor the United States can obtain it, nor are other companies in Germany. Only they own it. Dongfang has never imported this kind of engine at all. This is the first time it has been exposed to it, so it cannot be a leak.
If it is not a leak, that is to say, this drawing was drawn by themselves, they have already mastered the principle of the twelve-phase alternator?
“Lambert, please invite Mr. Harrington over!” Erich said.
However, seeing Erich's serious expression, Lambert had no other choice but to go out and make a phone call.
Ma Ming, on the other hand, has already started analyzing the drawings.
"Okay, since you said that the design drawing is the same as ours, then this problem cannot be avoided." Ma Ming said: "Let's analyze it in detail."
…
"This is the problem of the inherent oscillation encountered by the twelve-phase alternator. It is like Brownian motion. It has no rules, cannot be prevented, and has no symptoms. However, if it occurs, it will cause the equipment to completely lose power, and the consequences will be too great. Horrible." Ma Ming's analysis finally ended, and at the same time, a series of formulas and calculations were written down in the blank space next to the design drawing.
“Compared with the theory you are talking about now, I don’t understand it at all. The so-called natural oscillation problem is even more bizarre. I think…”
Hmm, this is just putting your face up to let yourself be beaten! Qin Tao was extremely excited and planned to say a few domineering words, but at this time Ma Ming had already looked at him with a pair of deep eyes.
“You don’t understand, I can teach you, sir, we are discussing science!”
The translator was stunned on the side, and Qin Tao smiled on the side, okay, Ma Ming said it, as long as he was domineering enough.
For many years, foreigners have been teaching the Chinese. Not long ago, Qin Tao also spent a huge sum of money to introduce the patent for membrane type natural gas ships. Now, it is finally the turn of foreigners to ask us for advice!
Enjoyable and relieve your anger!
“Literal translation! Add another sentence, I don’t charge any money and teach for free!”
Erich was stunned on the spot, as if he had been struck by lightning.
You don’t understand, I can teach you! This sentence shocked Erich so much that it kept repeating in Erich's mind.
You don’t understand, I can teach you! If you don’t understand, I can teach you!
“Can we take this drawing back and study it?” At this moment, another voice came.
I don’t know when, Harrington came in. He stood behind the drawings, looking at the tedious calculations, frowning in thought, until now, he finally spoke.
He is the inventor of polyphase alternator technology! He is the best in this field! Now, of course, he couldn't let Ma Ming teach him a second time. He had to look at these formulas and study them himself.
"sure."
“Dear guests, we are deeply sorry for delaying your trip because we are studying this issue. All your expenses here will be paid by our company.”
Lambert, who knew nothing about technology and only knew about sales, was shocked. He would never have imagined that Harrington, the company's chief engineer, major shareholder, and technology guru, would have such a low profile!
"Thank you." Zheng Ming was also filled with emotion. In the past, it was difficult to negotiate because foreigners were all superior, but now? Now it's our turn to be awesome!
Sure enough, it was right to bring Ma Ming here. Ma Ming is so awesome, and Mr. Qin is really wise!
Qin Tao and the others went back to the hotel to rest. Harrington immediately took the most capable technical staff in the company to start research. Late at night, in their company's laboratory, a twelve-phase generator for testing miraculously This inherent oscillation phenomenon occurs.
Only very special circumstances can induce this kind of oscillation, but once it occurs, it is absolutely catastrophic!
Harrington frowned: "Thanks to this young engineer, if he hadn't discovered this fault, our equipment would have been running with hidden dangers. At some point, if it broke out, it would be catastrophic!"
Among other things, these generators have been widely used in German-built submarines. Think about it, the submarine is charging in the snorkel state, and suddenly the generator stops and the entire submarine loses power. The submarine soldiers underwater , what fear and despair it must be!
The problem is discovered, then the next step is how to solve the problem.
"On the generator, we have achieved perfection and there is no better way. If we want to solve the problem of natural oscillation, we need to find a way later and arrange the relevant compensation circuit behind the rectifier circuit, so that That will solve the problem," Harrington said.
If the generator itself cannot be solved, we have to find ways to compensate for it later. Harrington, the technical master, spoke up, and everyone else could only follow suit.
But how can we solve it?
This is hard to say.
"Should we ask Easterners to study it? Since they have raised this flaw, they may have a solution." Erich spoke.
Harrington shook his head: "No, the twelve-phase alternator was developed by us. If there are problems, of course we need to solve them. Looking through the literature, especially the invention patents in recent years, I believe that we Europeans He is smart and must have solutions to relevant problems!”
So the technicians came to the library and started reading.
Time passed little by little, and the eastern sky slowly lit up. Suddenly, Erich shouted excitedly: "I found it, I found it. In the authoritative British publication "DERWENT", there is a special report with rectification. Patented invention for load stabilizing device for multi-phase synchronous motors! Great, great!”
Although they searched all night, they finally got something. As long as they can buy the patent, they can solve this problem.
Sure enough, they Westerners are smarter.
Harrington also became excited. Just now, he was so tired that he fell asleep. Now, when he heard about the patent, he ran over immediately, which was completely inappropriate for his age.
“Who is the inventor? We will contact you immediately.”
"China, Naval Engineering University, first inventor, Ma Ming." After reading the owner of the invention patent entry, Erich was immediately excited: "Yesterday, the person who raised this question with us seemed to be also named Ma Ming. Ming? Will it be..."
The circles in this kind of professional field are usually very small. Yesterday, Ma Ming's explanation was still in front of him, and the sentence came to Erich's mind: "If you don't know it, I can teach you." ah!"
For some reason, Erich shivered.
hotel.
“Ma Gong, Lao Zheng and I went for a walk on the street and bought some things on the way back. Do you want to come with us?” Qin Tao asked Ma Ming.
"No need." Ma Ming sat in front of the table, spread out his notebook, and was still writing something. For him, time was very precious, and he didn't want to waste it.
咚咚!
Not long after Qin Tao and Zheng Ming went out, there was a knock on the door. Ma Ming thought it was Qin Tao who had forgotten to bring something, so he went to open the door. However, the person standing at the door made him stunned.
"Mr. Harrington?" Ma Ming knew yesterday that the person who took away his drawings was the founder of multi-phase generator technology. He was a very good person. However, Ma Ming had nothing to fear. For him, he has this kind of momentum that a newborn calf is not afraid of tigers. How about authority? When three people are walking together, there must be a teacher like me, and there will always be something he doesn’t know how to do.
"It's me, Mr. Ma, your technology is too strong." Harrington came in, sat on the chair, and looked at Ma Ming: "The natural oscillation you mentioned really exists in our generator. Now , on behalf of the company, I sincerely invite you to help us solve this technical problem, and we will give you 1.5 million marks as a reward."
1500000! Deutsche Mark! If converted into RMB, it would be seven to eight million!
In 1992, it was absolutely unbelievable that an ordinary person could control this kind of wealth. In an era when ordinary people's monthly salary was only two to three hundred, with a wealth of several million, he would probably be on the rich list.
The translator brought by Harrington spoke out his words, while he was observing Ma Ming's expression.
"If you want, you can stay in Germany and work as a technical consultant in our company, and you can get a monthly salary of 100,000 marks." Facing the expressionless Ma Ming, Harrington continued to increase the amount.
"I thought of it! Wait a minute!" Ma Ming said suddenly, then ran to the notebook and messed with it.
Half done, Ma Ming was still thinking about technical issues just now!
Harrington was embarrassed.
After Ma Ming finished solving the problem, he looked at Harrington: "I'm sorry, what did you just say?"
Harrington could only repeat what he said.
"This." Ma Ming said: "How can you be so sure that I have a way to solve this inherent oscillation problem?"
“Because of this, you have just applied for a patent for a multi-phase synchronous motor stabilizing device with a rectified load. We think this can solve our problem.”
Ma Ming was so happy in his heart. Although the name was called a multi-phase motor, in fact, he was studying three-phase motors because there was nothing else. He did not expect that this invention could actually solve the problem of twelve-phase AC. The problem of inherent oscillation of the motor!
What is this called? No matter how hard you try, you won't be able to find anything. It takes no effort at all to get there!
Seeing Ma Ming's expression, Harrington thought he agreed: "In that case, I hope we can cooperate happily."
“I’m sorry, the patented technology property rights not only belong to me, but also to China.” Ma Ming’s answer was sonorous and powerful: “Since I was born Chinese, then everything I own also belongs to my motherland!”
“You need to purchase our invention patent, and then disclose to us the detailed technical data of the twelve-phase alternator, and then, in China, we can jointly solve this problem.”
